WIND FLY SCAR-ER.

Application filed March '2, 1927. Serial No. 173,294.

A further object of this invention is to provide a fly scarer that is adaptable to right or left hand opening closures.

li ith these and other objects in view reference is now had to the accompanying drawings in which Fig. 1 is a. perspective view 01": a closure and frame showing the device attached;

Fig. 2 is a sectional side elevation of a fragment of the device;

Fig. 3 is a plan view of the operating lever;

Fig. l is a side elevation thereof; and

Fig. 5 is a plan view from below of the bellows showing method of reversing the operating lever.

Having reference to the drawings like numerals refer to like parts throughout the several views. and the numeral 1 refers to a closure which may be of the screen door variety, or similar door, opening on hinges 2 supporting the door from a trame .3 consisting of side'pieces i and the top piece 5.

Let it here be understood that while reference is being made throughout the specitications to the frame as a means of support for the device, it is obvious that it may be attached to a side wall as well.

The device consists of awind supplying means 6 comprising preferably a bellows 7 having the usual upper plate 8 and lower plate 9, the upper plate being stationary in this case and attached to the frame by bracic ets 1!). and the lower plate being movably attached at the inner end to the upper plate 8 by the usual flexible connection 11. The lower plate is provided with nozzles 12 that are directed towards the closure. and these nozzles, by the movement of the lower plate during operation will change the direction of a blast of wind therethrough so that it will follow the closure its movement of opening or closing. and a valve 13 is pro vided to admit air to the bellows as it is expanded.

A weight 14 may be confined within the bellows or attached thereto to maintain the bellows in the expanded position, it is ob b that spring {not shown) may be interposed between the top and bot tom plates, in the usual. manner of such construction, :tor the same purpose.

During operation the lower plate has a general up and down m vement and ribbons 5 may be attached to the edge of the lower plate, to be agitated by the deflected current oi wind striking the ribbons during the movement of this member.

To operate the bellows a reversible operating; lever .16 is provided which in plan is of a generally circular form, with tangentially positioned ends 17 adapted for engagement by clips 18 secured to either end of the lower plate 9 of the bellows.

By this form of lever the lever may be attached at either end of the bellows to register with the closure constantly during its movement in opening and closing, and whether the closure is hung to operate from the left hand or right hand side of the frame.

The reversible lever is provided with depressions 19 and 20, oi equal distance from the ends of the tangent, and of equal form, with a central raise 21.

Attached to the upper part of the closure a roller 22 is provided for engagement with the operating lever and it is obvious that during the movement of the closure the roller will contact the lever providing for a gradually increased contraction of the bellows and an alternating expansion as thrroller encounters the depressions 19 and 20, with a maximum contraction obtaining as the roller engages what might be termed the high point 21 of the lever.

From this description it is obvious that an alternate up and down movement of the bellows will obtain during the movement of the closure in either direction of opening or closing, and by this means the wind is forced against the door in gusts, the ribbon is agitated by this movement of the lower plate, and with the wind following the door as the lower plate raises and the door is moving the combination will be highly effective for the purpose tor which it is intended.

In operation the brackets are secured to the frame, the bellows 7 is'attached to the bracketsor suitable support thereby, and the reversible operating lever is attached to the respective clip 18 that is above the hinged side of the closure.

The roller then attached to the closure and with this new a'ubly upon the move lltl nient of the closure any flies or other insects lodged thereon will be frightened by the ribbon and dislodged by the wind, until the door has had opportunity to resume its closed position.

\Vhile the device is an ellicicnt tly scarer it is obvious that it may be arranged as to sur face dimensions of the top plate to admit of being utilized as a shade or awning over the closure.

Having thus described my invention, I claim:

1. In a wind fly scarer, a closure, a bellows attached adjacent to said closure, and means adapted to operate said bellows with the movement of said closure.

2. In a. wind fly scar-er, a closure, a bellows attached adjacent to said closure, and a reversible operating lever adapted to operate said bellows with the movement of said clo" sure.

23. In a wind fly scarer, a closure, a lJUllUWr. attached to the frame of said closure, and a reversible operating lever attached to said bellows and adapted to register constantly with the closure during, the movement of that nieinber.

at. In a ll; sear-er, a closure, a roller hear-- ing attached to said closure, a bellows at tached to the frame of said closure, ribbons attached to said bellows and positioned for agitation by the wind therefrom, and a rcversible operating lerer attached to said bellows in register with said roller bearing, said lever being formed to provide an altcrnatinp; expansion and contraction of said bellows during the movement of the closure in either direction.

In testin'lony whereof I have allixed mr signature.

FREDERICK E. SHARP.
